This design is the upgard of firmware of the original TIDM-2PHASE-SUBMTR. This upgrade add functionalities and flexibility to the original firmware including : I2C communication capability, fundmental voltage and current measurment, voltage anc current THD measurement, reengineering of the the architecture allows flexible re-assignment of ADC channels.


•Measures AC frequency, RMS voltage, RMS current; Fundmental voltage, fundamental current, P active, P reactive, P apparent, power factor in better than 0.5% accuracy
•Flexible re-assignemnt of ADC channels
•I2C (slave mode) communication capability
